City residents rocked Thursday at a benefit concert for victims of the deadly Boston Marathon bombing, jamming to songs from the Dropkick Murphys, Boston and other musical acts and even laughing at a joke about the capture of a bombing suspect.

The Boston Strong Concert kicked off with the rock band Boston playing songs including its 1970s hit "More Than a Feeling."

"Tonight, we are all Boston," lead singer Tommy DeCarlo declared to a crowd of thousands of people, including victims and first responders, at the TD Garden.

The Dropkick Murphys, whose rousing rendition of "I'm Shipping Up to Boston" was a crowd favorite, were introduced by former New England Patriots player Joe Andruzzi, who was watching the April 15 marathon when the bombs went off and helped victims at the scene.

"When I looked around that day, the image that's in my mind is seeing more people run to the site than run away," Andruzzi said. "That is truly Boston Strong."
